6.3 SELECTING THE PROPER BLADE AND CUTTING SPEED
In cold sawing, there is no such thing as a general purpose blade. To achieve the best results from your
saw, proper blade selection is important. Each saw is shipped with a pitch (number of teeth) calculator,
which will help to determine the proper blade for your application.
When sawing flat stock or rectangular solid sections, determine the thickest section that will be cut and
use the equivalent square size on the pitch calculator to determine the proper blade.
The CPO-350 Variable Speed saw is designed to use a maximum 14 inch (350mm) diameter blade. We
recommend using smaller diameter blades if your application does not require the maximum diameter.
Using smaller diameter blades reduces the surface feet per minute and smaller blades provide greater
rigidity. Smaller diameter blades available from stock for this machine are a 12-1/2 inch (315mm) and a
10-3/4 inch (275mm). For available tooth styles in stock, REFER TO SECTION 11.0.
The chart below gives the surface feet per minute for the various diameter blades.

The proper blade speed is also important. The CPO-350 Variable Speed has an RPM range from 11 to
176. The heavier the material, the lower the RPM. The lighter the material, the higher the RPM.
